The grips save on using hand tape. In addition to pull-ups they can be used for deadlifts and kettlebells. You can potentially find an application for these grips in any exercise that is grip intensive. The leather, while not stiff, can be softened further with use and time, they will become more comfortable. Note: Please visit size chart X-Small-6.5 cm,Small-7.5 cm, Medium-8.5 cm, Large-10 cm
